And yet I agree. Looking through the lens of history, those that would disarm us are historically colored both Red and Blue, and our Big R friends have backed and enacted as much antiRKBA legislation as our Big D friends.
Using inaccurate labels for our foes can only lead to a misapplication of resistance.
I think it is easy to just split the world up into 'us' and 'them' along convenient and (unfortunately) intellectually lazy lines.
The 'us' in this case are people who believe that the RKBA is a natural right that is secured by the 2A, and the 'them' are people who would infringe on that right for many different reasons.
Because there are many different reasons, those foes and threats come from many different places, including BOTH sides of the political spectrum AND even from within the "pro gun" community. I've read plenty of letters to the editor from "gun people" who are perfectly willing to sell out "assault weapons", so long as it doesn't infringe on whatever firearms they like.
Here's a perfect example:
http://www.philly.com/philly/news/local/20121228_Stu_Bykofsky_.html
Stu starts off with a nice argument about how "why" isn't a valid argument against firearms ownership by responsible citizens, and then later in the article apparently feels that the rules are different for responsible citizens who own "military-style rifles" (apparently not understanding that just about every rifle today has origins as a military firearm).
Sen Feinstein's proposal has overshot just the "military style rifles" and is looking for anything semiautomatic, including pistols. She basically proposes limiting gun owners to choose from anything designed before 1900. Is she has her way, we're all going to be able to "bear arms" like the Colt SAA and the Winchester 1894 lever action, and that will be called "sensible restrictions".
The Cowboy Action Shooters and the hunters will shrug their shoulders at this law, and not care about the loss of ability to buy or own a Glock or AR....right up until some idiot shoots up a movie theater with a pair of six-shooters, and then the gun control advocates will be asking for another round of "sensible restrictions" on the "high power handguns" that are only "designed to kill people". They'll be playing the clip from Dirty Harry in an endless loop, showing how we need to get "the most powerful handgun in the world, the .44 magnum" off the streets! DO IT FOR THE CHILDREN!

What we need here is to STICK TOGETHER as supporters of rights and liberties for firearms owners. We are ALL under attack. It may not be your choice of firearm today, but given the slippery slope, it may be your choice on the chopping block next. And it won't matter who you voted for, what party you are registered with, or what your religious or political leanings are: we will ALL have lost an important right.
